To all whom it may 00mm:

Be it known that I, GLENN B. Biurrroit, a'citizen of'the United States, residin; Akron, in the county ofsumrniteud of Ohio,- have invented certain new and ful- Improvements in Processes and Pip ratus for Treating Rubber, of which the lowing is e specification. 1

This invention relates to an apparatus for use in the process or rubber inunuiiecture and is particularly, though not exclusively, designed to dry the sheets'oi rew rubber as they come i roin the washing 1 niechinesi i i, 1 i

The object 'oi'this ini ion a meens by Which nioistor wet sheets or rubber may be dried and pre zued in it much-"less ti Liethen required ut present,

Hereto'fore, the sheets of rubber have hung up in heated chambers un'tii properly dried "and aged, it taking from about thi; hours to one Week to thoroughly dry and age the material. With my improved method the rubber is treated in s, s tion of the time *iiormcrly required while obtaining the SELHIO results. I i

' My invention provides an apparatus that i requires very little floor one iii-Which material may be fed in it continu so ous strip if desired; it corutempietesi 1* use of the drying apparatus in connection Witcs; series of Weshii K continuous sp ere. s for severally Washing; and drying; strips of material of great length.

of one form of nmchine t at may l e used to accomplish the purpose of this invention. it shows the drying); apparatus ed cent the iv'sshing nmchiues to eiiniinete unmcessery handling of the IllittGllztl.

The rubber M is first thoroug'i'ily cleansed in the washing machine 1 by passing' it between a pair of squeeze roiiers 2 under it stream of Water supplied from s. spray pipe 8, this being the ordinary Well-known type of Washing machine. Fron the washers the Wet sheeted rubber is taken or fed directly to the drying apparatus.

In drying); the stock, in this selected embodiment of this invention it first subre'a itilcbly secured iachines to; produce a forminey be used to rot Y The above and other objects of this The single figure is a) diagrammatic View .lected tonir blasts lire-in the'nozzie 8; which chines is in n crini tiy, rugose sheer, having numerous crevices and smell itpertures in its suri in which retained considerable amount oi? the Water re'ceivet in the washing rnuchine. The air blast pleyino" on both sides oi the sheet b ows out most ot the waterfrorni ilepressions.

The sheet of rubiiier is then "ted into the drying; apparatus between a, pair of flexible belts 6 end, 7. The belts v6 and '3' may be made of any suitable roster'iel but are -orc'l erebly porous so that IDOiSCIF roe-y scape through belts. They convey the riel over it phufulity of heated drums 4 in e framework 5 and also confine the rubber geinst undue expansion or bubbiirur, as likely tocccur when eppi n heat to rubber containing Mi duets the high humidity conti ns betu ecn the bolts therubber is dried rzumll iwvitho iiuryr 7 At the outlet end oi? he machine is goi utter cooled rolierfi), over which the asses.
